I have a simple class that I want to install as Rails Metal. I don't want to put it into a file in app/metal for reasons I don't want to go into. It looks like this, and handler is defined elsewhere. class UrlFilter
ALLOW = [404]
DENY = [403]
def self.call(env)
handler.call(env["PATH_INFO"]) ? ALLOW : DENY
end
end I've tried installing it like this :
ActionController::Dispatcher.middleware.use UrlFilter but on the first request it crashes with : Sat Apr 03 00:29:43 +0800 2010: Read error: #<ArgumentError: wrong

script/server:3 The rails calling code looks like this : def klass
if @klass.respond_to?(:call)
@klass.call
elsif @klass.is_a?(Class)
@klass
else
@klass.to_s.constantize
end
rescue NameError
@klass
end def active?
return false unless klass if @conditional.respond_to?(:call)
@conditional.call
else
@conditional
end
end Notice when calling call no arguments are passed (twice!) ? Every metal
example I've seen defines the entry method as def self.call(env) yet this calling code doesn't pass any. Whats going on ? How do I define and install a metal class in code ?

I am using RoR 2.3, and have installed the builder gem I have a line in a view as follows: str_xml = render "fusioncharts/array_example/ss_array_data.builder",
{:arr_data => @arr_data} Which does not set str_xml to anything. I can confirm that in my controller I have @arr_data set up and
populated properly. (And in my controller, I have require 'builder'
at the top) In my views folder, I have a folder set up under it as "fusioncharts/
array_example/" and the file ss_array_data.builder. (However, this may
be why str_xml is not being set -- when I go to the URL which would
invoke this view, I get "Missing template _ss_array_data.builder in
view path..." It will only render the page if I put the underscore
before the filename ss_array_data.builder, making it a partial). What am I not understanding about builders that I cannot convert my
array @arr_data to str_xml ? Thanks so much, RVince --

A quick browse through your code shows that you can set options for a product, but where were you planning on storing the information from the user? I don't see any changes to the line_items table (or a separate table), etc to store the personalization input from the user. It also appears that each product can only have a single
personalization option. Is this your goal? I have the need for something similar, but I need multiple
personalization options per product, and it needs to support more
options than a single text field (some "personalization" needs to be
radio buttons, select boxes, etc). I would also merge your migrations right now while nobody is really
using the code. The way your migrations are currently written, if
someone was using a version that used the :personalisation_options
column inside products or variants, those changes would be lost when
you ran the 20100320220929_add_personalisable.rb migration since you
don't alter the name of the column, you drop it then re-create it. Of
course during the drop you lose any data that was entered by the admin
in that column. I assume that you are making the assumption that
nobody is using that previous version so it is ok to make the drop,
but if that's the case then you may as well clean up the migrations to
create the proper column to begin with. (Just my $0.02 on the
migrations) -Chris On Sat, Apr 3, 2010 at 6:24 AM, peachygifts <m.ward@leythers.com> wrote:

By any chance do you have a model named PageType? If you, you could set up a relationship between PageType and Page: page.rb:
belongs_to :page_type page_type.rb:
has_many :pages Then display it with: your_controller.rb:
@page_types = PageType.all your_view.html.haml (or .erb, etc.)
- @page_types.each do |page_type|
%h1= page_type.name
%ul
= list_of page_type.pages do |page|
= page.name If you don't already have a PageType model, or don't want to introduce
another model, you could probably use: @page_types = Page.all(:order => 'page_type', :group => 'page_type') and then play around with the result of that. (At least I think that's
correct… haha, sorry if it's not) Good luck,
